Exported JAR file does not show images

I have a Java project in Eclipse. This is the folder structure:

Eclipse folder structure

The code packages are located in src, and all images are in the res folder.

Images in the code are referenced like this:

new ImageIcon("res/settings.gif");

However, after I export the project to a JAR file (by using Export -> Runnable JAR File in Eclipse), and run the JAR, no images are shown. If I open the JAR with WinRAR, this is its structure:

JAR structure

All images are in the root folder, and can't be references correctly. How do I properly reference the images so that they are visible both from Eclipse and from the exported JAR?

I think I found the fix:

Replace this

new ImageIcon("res/settings.gif");

with

new ImageIcon(this.getClass().getResource("/settings.gif"));

Works both from Eclipse and from a runnable JAR file.

The res/ folder is not created in the .jar file. It looks that the resource location should not be "res/settings.gif" but "/settings.gif".

You are getting it to work if you debug in Eclipse because the home directory would be the root of your project, where the res/ folder actually exists.

The solution would be either to use an absolute path

new ImageIcon("/settings.gif");

or ensure that the res folder is copied into the jar. Maybe src/res or mark the folder as source folder in eclipse; I now am in another IDE.

Then it would be

new ImageIcon("/res/settings.gif");
